The present invention provides a transition metal compound, a catalyst composition comprising the same, and a method for producing an olefin polymer using the catalyst composition, the transition metal compound being capable of exhibiting high activity in olefin polymerization reaction, and also being capable of easily controlling the physical properties of an olefin polymer. When the transition metal compound is used, it is possible to provide an olefin polymer having an excellent energy-saving effect at the time of processing or molding.
